GL extruders

Gearless (GL) single screw extruder series with high-torque drive concept

The GL (= gearless) extruder series offer an alternative drive concept. A frequency-controlled, high-torque AC motor is used to drive the screw, with the screw and the motor’s output shaft forming a single line. The high-torque AC motor has a high degree of efficiency at all levels – even under partial load. Since the drives of the GL series operate without gears, all those energy losses caused by a gear transmission system, such as flange loss or heating, are also eliminated. 

The alternative drive concept 

Your Advantages:

  • Virtually no expense for maintenance (no motor air filter servicing, no gearbox oil change) and consequently cost savings
  • Operation at low noise and vibration levels
  • Higher degree of efficiency in the extruder’s drive chain thanks to high-torque motor technology
  • Smaller footprint with easy access

Our Offer:

  • Water-cooled, high-torque AC motor for low energy consumption
  • Reduced number of drive components
  • Compact design
